Abstract
Methods, analytical devices and analytical systems are provided for determining at least one analyte concentration in a body fluid sample. The methods, which may be incorporated into the devices and systems, can include the following steps: applying a body fluid to a test carrier; illuminating the test carrier by at least one light source, where the at least one light source is modulated by using at least two modulation frequencies; receiving light remitted by the test carrier by using at least one detector; determining an analyte concentration by evaluating at least one detector signal generated by the detector, where the detector signal is demodulated with the at least two modulation frequencies to generate at least two demodulated detector signals, each demodulated signal corresponding to one of the modulation frequencies; and detecting a fault by comparing the at least two demodulated detector signals.
